Abstract

A wall bed is disclosed employing a linkage assembly which moves the wall bed outwardly from a wall or cabinet in a fashion so that the head end of the bed will not be in the cavity and the level of the mattress will be at a height which approximately corresponds to the height of conventional beds. Three counter-balancing spring assemblies are disclosed. One employs an angle member which connects extension springs to the bed base so that they are contained within a compact structure which is received within the cavity. The second employs a linkage assembly having short and long links pivotably connected to each other by their ends, with an extension spring connected to the short link and a mounting frame. The third employs a linkage assembly with extension springs that neutralize the counter-balancing force when the wall bed is open to eliminate floating. A headboard is also provided which may be tilted rearwardly or positioned at a right angle to the sleeping surface.
